Within the Fifth Generation framework of dynamic network topology and moving cells, the nomadic node (NN) concept is seen as a promising paradigm to provide coverage extension and capacity improvement on demand as well as to attain reduced capital expenditure and operational expenditure when compared with fixed-node deployment, such as microcells. This paper proposes an enabling architecture for the NN operation in the framework of a wireless network, and then analyzes the physical layer aspects of the problem and investigates the performance of NN operation in the context of a realistic multi-cellular wireless network, with the help of site-specific propagation modeling and real geographical databases.
The produced results provide useful insights into the performance of the NN operation; the results show that the NN operation is beneficial both in line-of-sight and non-line-of-sight scenarios and demonstrate that the NN selection strategy, which is based on the backhaul signal-to-interference-plus-noise ratio with a 10 dB power window, offers almost identical performance with the optimum end-to-end throughput algorithm.
